Learn About Open Source

Open Source is an approach to the design and development of software. By making source code publicly available, Open Source fosters peer-based collaboration which in turn results in effective, large scale projects without the need for significant investment - and therefore ownership - by any one party.

Concentric Sky is a strong believer in the philosophy of Open Source and makes wide use of Open Source projects to offer significant savings to our customers. Where possible, we also contribute code back to the community to improve the software for everyone.

If you have questions about how we use Open Source to build web applications, feel free to contact us.
